II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 6,684,338 - "Apparatus and Method for Power Management of Computer System"

Issued January 27, 2004

The Invention Explained

• Problem Addressed: The patent describes a problem arising from the existence of different power management standards, such as Advanced Power Management (APM) and the more complex Advanced Configuration and Power Interface (ACPI) (’338 Patent, col. 2:50-61). Because these modes might cause a computer's power switch to behave differently (e.g., simple on/off versus suspend/resume), a user who is unaware of the current mode could accidentally turn off the machine and lose unsaved data (’338 Patent, col. 6:4-14).
• The Patented Solution: The invention proposes a computer system with a dedicated "indicating unit," such as a light-emitting diode (LED), that visually communicates the system's current power management state (e.g., APM or ACPI) to the user (’338 Patent, Abstract). This indicator is controlled by a microcontroller that detects the active power mode and ensures the indicator remains active even in a low-power state, allowing the user to correctly identify the system status before interacting with the power switch (’338 Patent, col. 8:26-34).
• Technical Importance: By providing an unambiguous visual cue for the active power management mode, the invention aimed to reduce user error and prevent data loss in an era when multiple, non-interchangeable power-saving standards were common in personal computers (’338 Patent, col. 6:11-14).

Key Claims at a Glance

• The complaint specifically asserts infringement of independent claim 14 (Compl. ¶2, p. 2).
• The essential elements of independent claim 14 are:
  • A computer apparatus, comprising:
  • a power management system including at least one state selected from among a first power mode and a second power mode;
  • a basic input-output system memory for storing a routine for setting the at least one state of said power management system;
  • a PMS state storage unit for storing the state of said power management system; and
  • an indicating unit for indicating the stored state of said power management system, said indicating unit corresponding to at least one selected from among a multi-color unit and a multiple-display unit.
• The complaint notes that Defendant is covered by "one or more claims" and the prayer for relief requests judgment on "one or more claims," potentially reserving the right to assert other claims, including dependent claims (Compl. ¶2, p. 2; Prayer for Relief ¶a).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the Okidata MB472w multifunction printer as the "Accused Instrumentality" (Compl. ¶2, p. 2).

Functionality and Market Context

• The complaint alleges the Okidata MB472w is a "computer apparatus" that includes a power management system with different power modes, such as "Power Save Mode" and "Sleep Mode" (Compl. ¶3). It is alleged to contain firmware (a basic input-output system) and non-volatile memory (a PMS state storage unit) to manage these states (Compl. ¶3). The key accused feature is an "indicating unit" that allegedly comprises the operator panel's backlight (which turns off in Power Save mode) and a "Power Save indicator" light that illuminates in green, thereby indicating the stored power state (Compl. ¶3). The complaint does not provide further detail on the product's market position. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

’338 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A primary dispute may concern the scope of the term "indicating unit... corresponding to at least one selected from among a multi-color unit and a multiple-display unit." The defense may argue that the combination of a general panel backlight turning off and a separate, single-color LED turning on does not meet the patent's more specific descriptions of a "multiple-display unit," which is described in one embodiment as having two distinct, labeled LEDs (e.g., "ACPI" and "APM") (’338 Patent, col. 6:45-59; Claim 16).
  • Technical Questions: A factual question may arise as to whether the accused printer’s "Power Save Mode" and "Sleep Mode" are distinct modes corresponding to the "first power mode" and "second power mode" of the claim, which the patent specification links to the specific APM and ACPI standards (’338 Patent, col. 6:30-34). The complaint does not provide evidence distinguishing the technical operation of these two modes in the accused product.

V. Key Claim Terms for Construction

• The Term: "indicating unit ... corresponding to at least one selected from among a multi-color unit and a multiple-display unit"
• Context and Importance: This term is the central limitation distinguishing the invention from prior art. The infringement analysis will depend on whether the accused product's combination of a backlight and a separate indicator light falls within the definition of either a "multi-color unit" or a "multiple-display unit." Practitioners may focus on this term because the complaint’s theory appears to conflate two separate components (a backlight and an indicator) into a single claimed "unit."
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes the indicating unit's purpose broadly as allowing a user to "identify the power management system state" (’338 Patent, col. 8:5-8). One could argue that any combination of visual cues that achieves this purpose, such as the one alleged in the complaint, falls within the claim's scope. The patent illustrates both a single integrated LED in a power switch (Fig. 5) and a separate panel with multiple indicators (Fig. 7), suggesting some flexibility in the form of the "unit."
  • Evidence for a Narrower Interpretation: Dependent claims 16 and 17 provide specific definitions. Claim 16 recites a "multiple-display unit" as comprising a "first unit" and a "second unit," each with specific labels ("ACPI" or "APM"). Claim 17 recites a "multicolor unit" as displaying a "first color" for the first power mode and a "second color" for the second power mode. A party could argue these definitions limit the scope of the terms in the independent claim, and that the accused functionality (one light off, one light on) meets neither of these more specific structures.

VI. Other Allegations

• Indirect Infringement: The complaint's jurisdictional section references indirect infringement under 35 U.S.C. § 271(b) (Compl. ¶3, p. 1). However, the substantive count for infringement only alleges direct infringement under § 271(a) and does not plead any specific facts to support the knowledge and intent required for an inducement claim (Compl. ¶2-3, p. 2-3).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. It does, however, ask the Court to "declare this an exceptional case and award Plaintiff reasonable attorneys' fees" under 35 U.S.C. § 285 (Compl., Prayer for Relief ¶d). The complaint pleads no factual basis, such as pre-suit knowledge of the patent, to support a finding of willfulness or exceptionality.

VII. Analyst’s Conclusion: Key Questions for the Case

This dispute appears to hinge on questions of claim scope and technical mapping. The key questions for the court will likely be:

1. A core issue will be one of definitional scope: Can the claim term "multiple-display unit," which the patent specification and dependent claims link to a component with two distinct, labeled indicators, be construed to read on the accused functionality, which consists of a general panel backlight turning off and a separate, single "Power Save" indicator turning on?

2. A key evidentiary question will be one of technical correspondence: Does the complaint provide sufficient evidence to demonstrate that the accused printer's "Power Save Mode" and "Sleep Mode" are technically distinct states that correspond to the "first power mode" and "second power mode" as contemplated by the patent, which are explicitly tied to the APM and ACPI standards?
